NCAAB DFS Lineup Simulator & Optimizer
College basketball DFS offers enormous player pools across hundreds of teams, with slates concentrated around conference play and March. Blowout risk is the defining variable — projected minutes evaporate fast when a 12-point favorite leads by 30 — and pricing is softer than the NBA's.
Why simulate NCAAB lineups?
With hundreds of rosterable players, NCAAB is a search problem before it's a projection problem. Simulation plus constraint filters (locks, blocks, exposure caps) turns an unmanageable pool into a ranked portfolio of lineups with quantified ceilings.
Correlated multivariate Monte Carlo is the key model here — it simulates teammates' outcomes moving together, which is what prices a stack's real ceiling.
Running a NCAAB simulation
- Pick a slate. Every slate loads its own player pool with base projections, salaries, and ownership estimates already merged in.
- Adjust the pool. Type new projections into the Proj column, lock players you're committed to, block players you want to fade, cap exposure per player, and set up stacking rules.
- Run the simulator. The engine iterates thousands of correlated lineups against your constraints and returns them ranked by leverage, ceiling, or projected points.
- Export site-formatted CSV. Upload directly to DraftKings, FanDuel, or Yahoo. The row order matches your ranked lineups so the top of the CSV is the top of your entries.
Slates lock at scheduled kickoff. Late-breaking news in the hour before lock routinely reshuffles projections, so the simulator's inline projection edits are designed for rapid last-minute adjustment.
Common NCAAB DFS mistakes the simulator catches
- Building without correlation. Two teammates who share a game outcome cannot be treated as independent — the simulator's correlated model prices the joint distribution correctly.
- Over-relying on point projections. The mean is only one number; the distribution's shape matters more for tournaments than for cash games, and simulation is how you see that shape.
- Ignoring exposure caps. Concentrated exposure to one player crushes portfolio-level variance — the simulator's exposure cap prevents accidental over-allocation.

NCAAB DFS questions
Can I simulate NCAAB DFS lineups?
Yes — DFS Simulator supports NCAAB (NCAA Men's Basketball) with positional rosters under a salary cap, where teammate correlation (stacks) drives tournament ceilings. Pick a slate, adjust projections, apply locks and blocks, run up to 50,000 iterations, and export site-formatted lineup CSVs.
When is NCAAB DFS in season?
NCAAB slates run roughly November – April. Outside that window the sport sits out of the slate picker until the season resumes.
Which DFS Simulator plan includes NCAAB?
NCAAB is one of the team-sport slots on every plan. Basic ($19.99/mo) picks 1 sport — many users choose NCAAB as that slot when the season is active. Pro ($49.99/mo) covers any 4 sports, so NCAAB sits alongside three others of your choice. Elite ($99.99/mo) includes all 21 sports plus advanced models and no cooldown on switching sport picks.
Which simulation models work best for NCAAB DFS?
Correlated multivariate Monte Carlo is the key model here — it simulates teammates' outcomes moving together, which is what prices a stack's real ceiling. Basic includes quasi-random Monte Carlo; Pro adds correlated MC; Elite unlocks genetic search and bootstrap resampling as well.
How does the simulator handle NCAAB slates?
The workflow is: pick a slate; adjust the pool; run the simulator; export site-formatted csv. Full step-by-step details are in the workflow section above.
When do NCAAB DFS slates lock?
Slates lock at scheduled kickoff. Late-breaking news in the hour before lock routinely reshuffles projections, so the simulator's inline projection edits are designed for rapid last-minute adjustment.
NCAAB DFS by site
Each DFS site scores NCAAB differently — roster shapes, salary caps, and scoring bonuses all shift optimal lineup construction. The per-site pages cover the specifics for the sport-site combination you actually play.
